After celebrating their 25th anniversary last year, pop-rock trio Hanson have announced the next stage of their career with the String Theory Symphonic Tour, which will land in Australia February-March 2019.

String Theory frames the trio's music - spanning the band's entire career from 'MmmBop' to 'Where's The Love' and 'This Time Around' to newer releases like 'Reaching For The Sky' and 'Siren Call' - through a special collaboration with Academy Award-winning arranger David Campbell.

There will be all-ages shows in Melbourne, Sydney, Canberra, Gold Coast and Brisbane.

The band will also release 'String Theory Double Album' on 9 November.
